Kiwis (New Zealanders) are internationally renowned for smoking joints down to the cardboard filter.
A "Kiwi pass" is when the roach is passed on to the next person and results in them burning their fingers and mouths if they try to inhale since there's nothing left.
Brought about because Kiwis smoke 100% pure joints and people from other countries mix their's with tobacco. Thus the very end of joints in NZ are still good but overseas they are less than good.
"What the hell are you passing that to me for, I dont want no kiwi pass!"
